4 Claims. (01. 65-13) The present invention relates to a novelconstruc'tion'ior liquid containers or devices assoraised from a.surface.

Particularly in the case of'containers used for cold liquids, iced.drinks, etc., the formation of condensed moisture on the exteriorsurface of the container presents a problem which up to the present timehas not been satisfactorily solved. This problem is more particularlyacute in the summertime when the humidity of the atmosphere is uniformlyhigher and the consumption of cold and iced drinks is more widespread.

As will be apparent from the following specification when considered inconnection with the accompanying drawings, the basic inventive ideaherein disclosed is susceptible of use in connection with a wide varietyof receptacles of the type normally used for serving cold or iceddrinks.

In the drawings,

Figure l is a side elevational view of a conventional drinking glass ortumbler having associated therewith a coaster embodying the improvementsof the present invention, the coaster being illustrated in section inorder to illustrate the improvements of the present invention.

Figure 2 is a bottom plan view of the improved coaster constructionshown in Figure 1. it

Figure 3 is aside elevational view of a conventional beverage bottleembodying the im-- provements of the present invention, the bottomportion thereof being illustrated in section to show the improvements ofthe present invention.

Figure 4 is a vertical sectional view through a drinking glass embodyingthe improvements of the present invention.

With more particular reference to the drawings, it will be seen that inall embodiments of the invention, it is contemplated that a capillarygroove or channel be provided in the base portion of the receptacle andit has been found that when the glass or bottle is raised from asurface, even a wet surface, the-accumulated moisture will accumulate inthe capillary groove instead of dripping from the receptacle-while inelevated position.

'In the construction shown in Figure 1 of the drawings, a conventionaldrinking glass I has associated therewith a coaster or separable baseportion 2 which, although detachable from the glass I, is preferablyconstructed in such away as to remain in assembled relation with respectto the glass during use. "This coaster :is preferably formed with anannular, upwardly extending flange 3 serving to provide a recess intowhich the base portion of the glasswillfit snugly enough to retain theglass. and coaster in assembled relation during normal use.

The underside of the coaster 2 comprises mainlypa fiat, plain surfacelwhich may ormay not be"relieved by a central depression 5/ Spacedinwardly from themarginal edge of the bottom ofl'the coaster is formedan annular groove or recess 6 which by means of capillary attractionwill serve to accumulate the condensed moisture which would normallydrip from the glass when the same was raised from a supporting surface.

ilWhile the particular material of which the coaster may be formed doesnot constitute a part ofi-the present invention, it has been found thatparticularly superior results can be obtained by forming the coaster byinjection molding from any one of a wide variety of well known plasticmaterials. This form of construction is advantageous because it is notonly economical for large scale production, but because it inherentlyresults in an accurate product.

frIt is of great importance that the intersection of the bottom surfaceof the coaster with the side walls of the channel 5 provide a preciseand sharp corner and, further, that the side walls of the roove 6 besubstantially parallel in order to obtain the maximum capillary effect.Injection molded plastics readily lend themselves to such ai'construction and make possible the provision of' an accurate andprecise article without the necessity of subsequent finishingoperations.

As is seen in Figure 3 of the drawings, a conventional beverage bottlemay easily be modified tdjincorporate' the improvements of the presentinvention. In this embodiment, the bottle I is provided with arelatively thick, heavy base portion 8 near the outer edge of which isformed a c illary groove or channel 9 similar in form, c nstruction, andfunction to the channel 8 described above in connection with thepreferred embodiment of the invention.

In Figure 4 is shown a tumbler which may be formed either of glass orplastic material. This tumbler I is likewise provided with a relativelyheavy, thick bottom wall II which has formed therein a capillary groove[2 which serves the same purpose as the capillary grooves or channels 6and 9 described above.

While the precise dimensions of the channels 6, 9, and I2 are notcritical, it has generally been found that'mos'tsatisfactory" resultswill be obtained if these channels are at least as deep as they are wideand that satisfactory capillary action will be obtained if the width ofthe channel ranges from one-sixteenthtonearly three-sixteenths of aninch.

Many other and further modifications of the invention falling within thescope thereof, as set forth in the following claims, will becomeapparent to those skilled in the art.

What is claimed is:

1. Areceptacle for. iced or cold beverages, said receptacle having sidewalls and a base portion having formed therein an annular capillarygroove, the intersections of the Side walls of said groove with thebottom surfaceof said receptacle forming a relatively sharp corner.

Q12. ALcfoaster for association. with" a; drinking glass, comprising acup-shaped,fupper 'portion adaptedto receive a drinking. glassf therein,and a base, portion having formed therein an annular capillary. groove,the intersections of the side walls of said groove with the bottomsurface of said coaster'm'ember forming a relatively sharp corner.

, 3. A drinking'l' glass for iced or cold beverages having walls andfabase portion, said basehav ing in its undensurfaQe'an. annular capillarygroove, the intersections of the side walls of said groove with the saidunder surface of said base portion forming a relatively sharp corner.

4. A bottle or similar container for iced 01' cold REFERENCES CITED Thefollowing references are of record in the file of this patent:
